Corpse bile touched the rice

[Hanuman]

I messed up and didn't notice a poorly placed, now rotting corpse () in a rice storage building. I cleaned up bile and tossed the rice touching the rotting lynx corpse, the rest of the rice I moved to a larger food storage area. My best pawn just got food poisoning :/ Should I have tossed ALL the rice instead of just the rice around the corpse/bile? Even worse, did I ruin the food in the larger farming storage area by bringing the rice in?

also, does vomit on floors and other pawns being near it cause disease in other pawns?

Food on the ground can't become poisoned, doesn't matter if it's sitting in bile, blood, vomit, whatever, it's all fine. The only time poisoning is checked is when the cook is making a meal, at that point it looks at the overall cleanliness of the room and if it's -2 or below it adds a chance for that meal to be poisoned. So just make sure your kitchen is cleanish while the cook is cooking and you are fine, no matter what awfulness the raw ingredients have been through.

All raw food always has a flat 2% chance to cause food poisoning when eaten.

Nothing causes disease, they are just a random event based on biome. Filth can cause infection if a pawn is treated while in a filthy environment, so it's good to have a clean room for treating patients.

Awesome, I was worried all my pawns will get food poisoning, its a huge debuff, haha he barely can walk. Thanks Astasia

Well, if a poisonous meal ends up in a stack of meals, the entire stack become poisonous, so more people may still get sick when it first happens.

so to expand on this i have a question... when you cook the 4X meals, is it 1 roll for all 4 or 4 rolls?

It's one roll for all 4. Meaning you will get a lot of sick people all at once if you use the batch meals, but there will be longer gaps between outbreaks.

While we're on the topic, we should note three things:

1) that nutrient paste can't give food poisoning

2) That butcher tables give rooms a cleanliness debuff so you should keep your butcher table and your stoves in separate rooms to help prevent food poisoning

3) Sterile tiles and metal tiles give a cleanliness buff to rooms so you should put those in your kitchen(though I believe sterile tiles give a higher cleanliness bonus) to help prevent food poisoning

No it doesn't. The 100% chance for for poisoning from the meal gets averaged across all the meals in the stack (so if it's added to a stack of 9, each meal has a 10% chance). It CAN cause more food poisoning than just the one poisoned meal would, but it just as easily can cause less.
It's far more relevant when you use the x4 recipe, since either every meal is safe or every meal is poisoned, so that stack of 4 will tend to cause a string of poisonings even when added to another stack. It's still not infecting the entire thing though, and will on average give you 4 poisonings.

Correct. Sterile tiles give 0.6 cleanliness whereas steel, silver, or gold tiles give 0.2.
